Trivia, insights & behind the scenes
Kelly spent years trying to get this made; MGM finally greenlit it after his success in Europe, then buried it with minimal US release. It lost money and effectively ended his directing career.
The animated Sinbad sequence — featuring Kelly dancing with cartoon characters — predates Mary Poppins' penguin dance by eight years and Roger Rabbit by thirty-two.
